  <!-- to animation: rotation from base value -180 to final value 90 but with
       other animations combined.

       What happens here is that the rotation animation can't interpolate from
       the base value as it's not a rotation transformation, so instead it
       assumes an underlying zero matrix as the base value. (see next comment)

  <!-- to animation: rotate and scale
       
       Here again the scale animation can't interpolate from its base value
       which is of a different type so it assumes a zero matrix NOT an identity
       matrix (this is what the SVG WG have decided in the SVGT1.2 Tiny test
       suite).
